Abstract

UN PROCEDIMIENTO PARA LA PRODUCCION DE ACETATO DE VINILO MEDIANTE LA REACCION DE ETILENO, OXIGENO Y ACIDO ACETICO COMO REACTIVOS, QUE CONSISTE EN PONER EN CONTACTO A DICHOS REACTIVOS Y UN COMPUESTO DE COBRE TAL COMO ACETATO CUPRICO DIHIDRATADO SIN CONTENIDO DE HALOGENO, CON UN CATALIZADOR QUE ESTA CONSTITUIDO POR UN SOPORTE POROSO DE SILICE, EN DONDE SE DEPOSITAN CANTIDADES CATALITICAMENTE EFECTIVAS DE PALADIO, ORO Y COBRE METALICO ADEMAS ESTE CATALIZADOR PUEDE CONTENER UN DEPOSITO DE UN ACETATO DE METAL ALCALINO. CADA LITRO DE CATALIZADOR CONTIENE: 1g-10g DE PALADIO, 0.5g-10g DE ORO, 0.3g-5g DE COBREA PROCEDURE FOR THE PRODUCTION OF VINYL ACETATE THROUGH THE REACTION OF ETHYLENE, OXYGEN, AND ACETIC ACID AS REAGENTS, WHICH CONSISTS OF CONTACTING SUCH REAGENTS AND A COPPER COMPOUND SUCH AS A CONTACT DIOCHYDRATE WITH NO CONTENT IT IS CONSTITUTED BY A POROUS SUPPORT OF SILICON, WHERE CATALYTICALLY EFFECTIVE AMOUNTS OF PALADIUM, GOLD AND METALLIC COPPER ARE DEPOSITED ALSO THIS CATALYST MAY CONTAIN A DEPOSIT OF AN ALKALINE METAL ACETATE. EACH LITER OF CATALYST CONTAINS: 1g-10g PALADIUM, 0.5g-10g GOLD, 0.3g-5g COPPER
